Laptop cooling pad, usb fan cable end replacement
I'm trying to fix a laptop cooling pad. The usb end broke off. So I figured, easy fix, found a spare usb end and soldered the wires together. No dice. It's a 2 fan setup, I assume wired in parallel. It's not really designed to be taken apart, so I can't get a good look at the set up. Lable on the pad says it's rated at 5V 0.45A 2.25W. I tried a few power sources, each time I get 5V before connecting the fans, and 2V after. I tried just wiring one, and got the same. Seems like it should have been the simplest fix, but I'm stumped.
Attached is a pic with it just connected to one fan.
